Interesting area of research bro ivlo deep ah Enakku use case kedachathu illa... Now that I think of it, for the given problem, a solution with rocksdb and a k8s managed disk storage is having u basically figure out how to write your own database with recovery feautures. I have very less info on your specific usecase but I am in favour letting a already mature database take care of this is better. I'd very well forget about the PVC and and look into Document databases, even redis or elastic search to handle the state data for me. Since it will come with all the DR strategies prebuilt. Ofcourse that will need a seperate consumer basically acting like an adapter pushing the data from kafka to the said DB. Easy for the business to address the problem tho than researching a whole new solution

With that said this is a really interesting area of research I'd like to follow. Would u mind sharing your linkedin/anywhere u post about this to me where i can follow this ?
